Talking about drive shafts.... 03 Nomad 40,000 U-joint came apart, but the crazy thing is... It was doing this for sometime, because the "yoke" were beating away at each other, "taking up the slack" of the failed U-joint. You would have thought that this thing was making a God awful noise, but it wasn't. All that to say, Yes, lube the splines/drive shaft is important, but in my opinion.... lube the U-joint!!! (Have you seen the itty bitty amount of cheap grease that is in a U-joint with the needle bearings), Unfortunately, the factory U-joint has No provisions for a grease fitting. Also, Kawasaki does not sell "just" a U-joint for the drive shaft of a Vulcan. You have to purchase the "complete" driveshaft/U-joint/Yoke assembly. Long story short, a Kawasaki Quad 4-wheeler 450 uses the same U-joint, I had to get this part (TEAM #UJ7002) through my local Honda dealer #31-41842 ( $24.95) Good Luck
